DS90LV032TMX - Quad LVDS Receiver | Texas Instruments
N.º da peça: DS90LV032TMX ✓ AtivoDS90LV032TMX Visão geral
A low-voltage differential signaling receiver is a line receiver that distinguishes the voltage difference between two conductors rather than the voltage referenced to ground. LVDS belongs to the broader interface-IC and data-converter interface hierarchy. Its differential architecture reduces sensitivity to common-mode noise, supports low-voltage signaling, and is commonly used when a system must transfer clock or data signals over a compact cable or PCB trace.
The DS90LV032TMX provides four receiver channels, operation beyond 400 Mbps, and translation of approximately 350 mV differential input signals to 3-V CMOS levels. Its four-channel arrangement allows one receiver package to handle four independent data paths or multiple clock and data lanes. The low-power design is useful when the receiver must operate close to high-speed processors, FPGAs, serializers, or test equipment without adding substantial system power.
Internally, the receiver compares the two differential inputs for each channel and uses the polarity of that voltage difference to recover the intended logic state. Differential detection rejects noise that appears equally on both inputs, while the CMOS output interface connects the recovered data to ordinary digital logic. The exact supply-voltage limits, propagation-delay limits, input-current limits, and temperature ratings should be taken from the manufacturer data sheet before finalizing a high-speed design.
Typical applications include LVDS clock distribution, camera and video interfaces, industrial control links, test-and-measurement equipment, and general-purpose high-speed digital connections. Quad-channel density is particularly attractive when a design needs several low-voltage differential inputs but has limited board space. The receiver can also support links operating below its maximum rated speed when the source amplitude, termination, trace geometry, and timing budget satisfy the interface requirements.
PCB implementation should preserve the differential characteristics of each input pair. Route the two conductors of a channel as a tightly coupled pair, provide the specified input termination, avoid stubs, and keep return-path discontinuities away from the signal traces. Differential impedance, receiver input capacitance, connector geometry, and source-edge rate can affect eye opening and therefore determine whether a nominal 400-Mbps-capable receiver maintains adequate margin.
This product overview combines the DS90LV032 family specifications, package information, sourcing context, and practical implementation guidance. It also distinguishes exact-family replacements from electrically similar receivers that may use different thresholds, supply rails, or pin arrangements, helping engineers narrow a replacement search before committing to a board-level substitution.

Aplicações típicas
DS90LV032TMX é adequado para 6 aplicaçãos: High-Speed LVDS Clock Distribution, Industrial Data Links, Video and Camera Interfaces, Test and Measurement Equipment, FPGA and Processor Data Interfaces, Communications Equipment.
High-Speed LVDS Clock Distribution
The DS90LV032TMX fits clock-receiving stages that require multiple low-voltage differential inputs converted to 3-V CMOS logic. Its four receiver channels allow one package to handle several clocks or a mix of clock and data lanes, while the specified capability above 400 Mbps supports high-speed digital systems. Place a source-side LVDS driver upstream and route each receiver pair as a coupled differential channel. Maintain controlled impedance, correct termination, and matched connector geometry so reflections do not consume the timing margin required for operation above 200 MHz.
Recomendado
Industrial Data Links
The DS90LV032TMX is suitable for industrial control equipment that receives clock or data from an LVDS transmitter over a compact cable or PCB connection. Four differential receiver channels reduce the number of packages needed when several interconnects share a controller or data-acquisition module. Its input handling centers on a typical 350 mV differential signal and converts it to a 3-V CMOS output for digital logic. Because industrial environments can introduce common-mode noise and ground-potential differences, use balanced routing, suitable grounding, and the manufacturer's specified termination network.
Recomendado
Video and Camera Interfaces
The DS90LV032TMX can receive multiple low-voltage differential lanes used by high-speed video, imaging, or synchronization systems. Its four channels are useful when a camera module, display controller, or frame-processing FPGA presents several clock and data pairs. Support beyond 400 Mbps makes the receiver appropriate for interfaces that require more than 200 MHz clocking, while the 3-V CMOS outputs connect naturally to digital logic. Preserve signal integrity by keeping each input pair closely coupled, minimizing connector and test-point discontinuities, and confirming that the source waveform remains within the receiver's valid input range.
Recomendado
Test and Measurement Equipment
The DS90LV032TMX is appropriate for instrumentation that must recover several low-amplitude differential signals and present them to CMOS logic. Its low-power architecture is valuable in multi-channel instruments where receiver density and power consumption both affect thermal design and rack density. The four receiver channels can handle separate measurement-control, synchronization, or acquisition lanes at rates exceeding 400 Mbps. Use short, controlled differential routes and provide clean reference planes to minimize signal degradation between the source, connectors, and receiver inputs.
Recomendado
FPGA and Processor Data Interfaces
The DS90LV032TMX can serve as the receiver stage between an LVDS source and an FPGA or processor that requires 3-V CMOS logic. Four channels support several incoming lanes without requiring one receiver package per signal. Capability above 400 Mbps is appropriate for high-speed fabric, control, and synchronization interfaces, but the design must account for source edge rate, trace loss, connector reflections, and input loading. Route each differential pair consistently and verify timing against the FPGA input requirements rather than treating the maximum advertised data rate as a guaranteed system throughput.
Recomendado
Communications Equipment
The DS90LV032TMX is suitable for communications equipment using point-to-point LVDS links for clock recovery, command data, or parallel data transport. The four-channel architecture improves board utilization when multiple receiver lanes terminate on one logic device. Its typical 350 mV differential input sensitivity and support for data rates above 400 Mbps align with compact, high-speed backplane or cable-based interconnects. Ensure the transmitter, receiver, connectors, and PCB geometry implement a common LVDS impedance and termination strategy, particularly when cables introduce additional skew or attenuation.

Notas de projeto
Route each LVDS input as a tightly coupled differential pair with symmetric geometry and a continuous reference plane. Keep both conductors of a pair over the same reference-plane region, avoid plane splits beneath the pair, and minimize test-pad and connector stubs. A discontinuity on only one conductor changes the differential impedance and can create reflections that reduce timing margin at data rates above 400 Mbps.
Use the termination arrangement specified by the Texas Instruments DS90LV032A application information and match it to the transmitter implementation. Check the source amplitude against the receiver's 350 mV typical input condition, then verify the complete link with the intended cable, connector, and PCB length. Do not add arbitrary termination or extra series resistance, because excessive damping can reduce edge rate while insufficient damping can increase reflections.
Do not assume that any four-channel differential receiver is electrically interchangeable with DS90LV032TMX. Input thresholds, common-mode range, supply voltage, fail-safe behavior, propagation delay, and enable or shutdown pin functions can differ. Compare the exact data sheets and land patterns before replacing the device, especially when the alternative uses an RS-422 or older CMOS differential receiver rather than the LVDS thresholds required by the original link.
Place the receiver close to the connector or source interface when cable loss and round-trip timing are significant. Keep the LVDS pairs away from clocks, switching regulators, and other high-slew-rate nets, and provide a quiet ground reference beneath the interface area. The device itself has no separate analog supply requirement stated for the exact ordering code, so board partitioning should follow the complete manufacturer application guidance.
